A sailboat having a triangular frame formed of three beams forming the sides of that frame and three pontoons or hulls disposed at the vertices of the triangle and extending outward from one side of the plane of the triangle. A mast extends outward from the other side of the plane and is connected to the vertices by cables to form a tetrahedral-type space frame which is structurally sound and easily dismantled.

A sailboat adapted to sail on water in a sailing direction that comprises, in combination: three rigid beams that form the sides of a triangle having a generally horizontal orientation, an integral, rigid mast that extends between top and foot ends and disposed substantially orthogonal to the plane of the triangle, the foot end of the mast being disposed within the perimeter of the triangle and piercing the plane of the triangle, a plurality of cables extending from each vertex of said triangle to said top and foot ends of said mast, the ones of said cables extending to the foot of said mast lying below the plane of said triangle, said cables being stretched to support the mast in said orthogonal orientation as well as to render a space frame defined by said beams, mast and cables rigid; three hulls positioned respectively at the three vertices of the triangle, and means for mounting said hulls to said vertices so that they each are rotatable about both a first axis generally parallel to the plane of said triangle and generally perpendicular to the sailing direction and a second axis raked backwardly from the sailing direction and from a normal to said triangle by an angle a
